APPARATUS FOR MELTING TALLOW, WAX, 84.0.

SPECIFICATION forming part of Letters Patent N o. 47*),023, dated June14, 1892. Application filed February 4, 1891. Serial No. 380,200. (Nomodel.)

To all whom it may concern:

Be it known that I, AUGUST SEIFFERT, a subject of the German Emperor,residing at Frankensteimin Silesia, Germany, have invented a new andImproved Apparatus for Melting Tallow, Tax, and other Substances, ofwhich the following is a specification.

This invention relates to an improved apparatus for melting tallow, wax,and other substances, and for extracting the tallow out of suet andgrease.

The invention consists in the various features of improvement more fullypointed out in the claim. 1

In the accompanying drawings, Figure 1 is a vertical central sectionthrough my apparatus. Fig. 2 is a similar section through amodification.

The letter a represents a cylindrical boiler having perforated sides anda perforated bottom. This boiler is placed into a second boiler l), thesides of which are perforated from the top down to a point Z). From thispoint the boiler b is solid.

c is a third entirely-solid boiler or casing that incloses' both theboilers ct l) and is provided with a cover (Z. This boiler is placedover a fireplacef, Fig. 1, or it is connected to a heat-generator by apipe 7t, Fig. 2.

In use water is poured into the boiler c to a point below the level I),and the heat is ad mitted to boil the water. The steam developed entersthrough the perforations of vessels b a and melts the suet, grease, orother material, which being liquefied will collect within the lowersolid part of boiler I). Here it is tapped by discharge-pipe e andcollected in a receiver g.

Within the boiler a a disk or piston h is secured to a screw-spindle i,by which it may be raised or lowered. This disk serves to press theliquid matter out of the mass toward the end of the operation. Themolten tallow or other substance, together with the condensed Water,will pass into the reservoir g in a pure state. The water will collectat the bottom of the receiver while the tallow or grease, being lighter,will separate and will solidify on cooling.

By my indirect mode of melting the grease a pure and uniform product isobtained. The process is rapid and by properly feeding fresh rawmaterial into the boiler large quantities may be treated in a shorttime.

What I claim is- The combination of an inner perforated boiler a with anintermediate boiler b, that is perforated on top, but solid at thebottom, an outer solid boiler c, a heat-generator, a dis charge-pipe e,and a piston within the inner boiler, substantially as specified.

In testimony whereof I hereunto sign my name, in the presence of twosubscribing witnesses, this 15th day of July, 1890.

AUGUST SEIFFERT.
